CHART FOR MEMORIZING WIRELESS CODES.

Application filed December 12, 1922. Serial No. cos 12s.

To all whom it may concern:

Be it known that I, CoRYnoN G. SNYDER, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Charts forMemorizingWireless Codes, of which the followin is a specification.

his invention relates to improvements in charts-for memorizing purposes.

The primary object of this invention is the provision of a chart, primarily adapted for use in connection with the memorizing of codes. a

A further object of this invention is he provision of a chart for code memorizing, embodying code signs arranged in such distinctive manner as to at once suggest the character which they re resent.

A further object of this invention is the provision of a chart for code memorizing, having certain characters delineated there- I on, and the code signs symbolic of the same arranged in contrasting conforming relation therewith, whereby apupil may in a minimum of time memorize the res ective code symbols of the characters, an recall the arrangement of signs of the code symbols with com arative ease. I

A furt er ob'ect of this invention is the provision of a 0 art of the above mentioned character, embodying a novel arrangement of code signs symbolic of a certain set of characters, so co-related that the code signs of certain characters are suggestive of the code signs of ,other characters.v

Other ob'ects and advantages of this invention will the following detailed description.

In the drawing wherein for the purpose of illustration is shown but the preferred embodiment of this invention, a set of alphabeticalcharacters are depicted, showing the international wireless .code symbols for the same, and in addition showing. the alpha- I betical characters and the contrasting conforming relation of the respective code sym-- bols thereof.

In the drawing wherein for the purpose of illustration is s own the chart in its preferred embodiment, the numeral 10 designates a set of characters, such as the-letters of the alphabet, which referably have code si nals 11 symbolic o the same disposed t erebelow. These symbols 11 are be apparent and inherent in preferably the international U wireless code symbols, and show the arrangement of the dot and dash signs 12' and 13 of said symbols for the respective characters of the set 10.

The novelty in the imfproved, chart consists in the association '0 letters 10 and their symbols 11, as to instantly impress upon the mind of the person the signs of the various symbols. To this end, the set of characters or letters 10 are the characters or each finely delineated on the chart, as dester is finely outlined with the signs of; the

code symbol heavily depicted in superposed contrastin relation thereon. A similar effect may e had by contrasting, in different colors, the character and its respective code symbol, and other means of contrastin the manner may suggest themselves.

There are four outstanding mechanical code symbol and its character in assoclated,

"-featur'es by means o which the pupil aided in memorizing and directly recalling the character of a code symbol, and vice versa, which are as follows:

First, The code signs which syinbolical- 1y designate a particular character are arranged substantially in the form of the" character which they represent.

= Second, The code si ns symbolic of the characters are delineate in superposed relation withthe character which the code signs represent. 4

Third, The code signs of the various code symbols are arranged substantially in the form of the character which they represent, and are readable in a continuous direction along the form of the character.

Fourth, The code si groups or symbols, an in the form of the character each group represents, in such manner that the arrangement of code signs of one character is suggestive of the ars are arranged in 1'05 rangement of code signs of other characters.

'ing relation with the character.

From the foregoing it can readily be understood that the code signs and symbols are directly associated with the character or letter which they represent. Thus, in the memorizin of the signs of the various code symbols, t ere are no words or phrases which must first be learned, as is necessary in most methods, systems, and charts for instruction of codes and the like. It is thus evident that the simplicity of the characters and their respective code symbols as taught by the improved chart, is an advantage over any means of memorizing a code -which necessitates the memorizing of words acters having somewhat similar shapes andcode symbols. In connection with the chart illustrated in the drawing, instructions may be forwarded the student either on the chart or on separate pamphlet, calling the students attention to the similarity of certain.

characters and the code symbols thereof. Thus, in connection withthe letter A, the following note can be given:

On A the horizontal bar is used for the dot and the slanting line on the right for the dash. Thus, we read from left to right; dot, dash. The central line of B, E, F, and H are also used for dots.

For the letter F, the following note may be given:

' With F we start by using the top line for two dots, then the upright for the dash, and the central line for the final dot. When we consider that L, is nearly the same shape inverted and that the code signals are ]l.1St the reverse, the two are very easily remembered.

For the letter. S the following note may be given: I

is easil remembered by itself or with B and or even 0. Nearly everyone knows that the distress call is S O S. And as S has three dots and 0 three dashes, the two are easily remembered byrthis, if for no other reason.

It can readily "be understood from the foregoing that notes may be used in con- -nection with each letter, which while not necessarily serving as a .part of the chart,

may serve to ,call the attention of certain inapt students to the relation of the various characters and the various symbols. Of

Leamee course, the ease of memorizing the code by means of the improved chart is based upon certain physiological principles, and for somestudents no great efiort of study will be required, and the notes in connection with the various characters may be dispensed with altogether.

The word character as used in this specification and the claims thereof is to be given a broad meaning, and may be interpreted 'to designate letters of the alphabet, numerals, punctuation marks, writing, printing, or other indicia. 4 It is to be noted that the dots have been designated on the chart as short strokes at an inclination to the vertical. This is done in order to facilitate code writing by the pupil, as it is more convenient to scribe a dot in the manner illustrated, and makes the dot more distinctive than if a round true dot were shown.

Features of the improved chart are of course susce tible of use in various other ways than t at herein described and illustrated. It is contemplated to utilize the features of the improved chart in connection with memorizing, translating, interpreting, etc.,' of various languages, studies, systems, and codes. Such changes will of course be made without departing from the spirit of the invention or the scope of the claims.

I claim:-

1. A chart for code memorizing comprising code delineations arranged substantially in the form of the characters they represent.

2. A chart for code memorizing comprising a plurality of groups of code delineations symbolic of certain characters, the 1 code delineations of each group being arranged substantially in the outline of the characters said grou represents.

3. A chart for co e memorizing comprising characters, and the code symbols of said characters, said characters and their respective code symbols being disposed in dis tinctive superposed relation.

4.A chart for code memorizing comprising finely outlined characters, and code symbols representative of said characters distinctively, displayed on said outlined characters.

5. A chart for code memorizing comprising finely outlined characters, and code delineations representative of said characters heavily displayed in conforming and contrasting relation with their respective characters.

6. Achart for code memorizing comprising a set of characters, and dot and dash code symbols for'said characters contrastingly' superposed onsaid characters.

.7. A chart for code memorizing com ris ing a set of characters, and International wireless code symbols therefor displayed in distinctive outlining relation with said tive of said characters displayed in contrasting'outlining relation with their respective characters and readable in a continuous direction along said characters.

9. A chart for code memorizing comprising characters, and code symbols for said characters disposed in super osed relation with said characters said cofie symbols 01 said characters being readable in a continuous direction along said characters.

10. A chart for code memorizing comprising a set of characters, and International wireless code symbols representative of the several characters in sa1d set, disposed in superposed relation therewith, symbols of certain characters being readable in a con-v tinuous direction along said characters.

11. A chart for code memorizing comprising code si ns arranged in groups and in the form of the character each group represents in such manner that the arrangement of code signs of one character is suggestive of the arrangement of code signs of other characters.
